Ghost presents downhill prototypes

Ghost will present a new DH model in spring. After no bikes with more than 160 millimetres of travel were in the range in 2009, a new 200-millimetre downhill machine will be launched this spring.

Ghost will present a new DH model in spring. After no more bikes with more than 160 millimeters of travel were in the range in 2009, a new 200-millimeter downhill machine will be launched this spring. The GHOST A.T.G. Pro Team (Marcus Klausmann) will also be competing with it in 2010.

Here are a few photos and information directly from Ghost in advance:
With a suspension travel of 200mm, the bike stands for an absolutely unique combination. This consists of (1) a very low average gear ratio of 2.25:1 (shock length 267mm with 89mm stroke), (2) a revolutionary GHOST proprietary needle bearing technology in the shock and (3) a "pedal kickback" eliminating idler pulley system. This triple combination guarantees first-class rear suspension performance.

The low transmission ratio provides more stroke per suspension travel. A larger moving oil volume results in better controllable oil flow control. On the one hand, this enables much more precise damping tuning and, on the other, the larger oil volume can better absorb the heat generated and dissipate it more effectively via a correspondingly larger cooling surface. As a result, the setting remains largely constant over the entire descent.

The use of a needle bearing in the shock eyelet (GHOST Needle Bearing System) reduces the frictional forces in the shock suspension to an absolute minimum. The friction values in the damper suspension are mainly responsible for the high breakaway torque. Because these breakaway torques have to be overcome several times per second during driving, there is an enormous gain to be made here. The elimination of these forces through the use of a needle bearing results in enormously sensitive and delicate response behavior.The bogey roll is an ingenious deflection roller system and is responsible for decoupling the pedal rebound forces from the spring system. This means that the suspension process is no longer affected by the weight of the rider acting on the pedals. By using the bogey roll, the chain extension is reduced to zero and no longer hinders the suspension process. Furthermore, a high swingarm pivot point is possible, which ensures an optimum wheel lift curve. The installation torques are much greater with a high swingarm pivot point, which in turn guarantees a much higher drive neutrality with a suspension that works absolutely free of influence.
The difference to conventional rear suspension systems is hugely noticeable.The models will be officially presented in spring.
